Meshing Theoretical Study and Simulation on Cylindrical Tri-sine Oscillating Tooth Gear Drive

The structure of cylindrical tri-sine oscillating tooth gear drive is presented. Based on the space meshing theory, equations of meshing and tooth profile are established and its meshing theory is studied. Using Pro/E, this system is modeled and simulated,which is compared with the above-established equations.     

Kinetics of Chlorine Decay in Water Distribution Systems

A combined first and second-order model, which includes bulk decay and wall decay, was developed to describe chlorine decay in water distribution systems. In the model the bulk decay has complex relationships with total organic carbon (TOC), the initial chlorine concentration and the temperature. Except for the initial stages they can be simplified into a linear increase with TOC, a linear decrease with initial chlorine concentration and an exponential relationship with the temperature. The model also explains why chlorine decays rapidly in the initial stages. The parameters of model are determined by deriving the best fitness with experimental data. And the accuracy of model has been verified by using the experimental data and the monitoring data in a distribution system.

不同光照条件下新疆小拟南芥(Arabidopsis Pumila)的表型可塑性研究

田间观测同一区域不同光照条件下小拟南芥可塑性变化,研究表明:1)阴阳两地小拟南芥在株高和茎生叶数、叶重、花序重、茎重、莲座叶重等特征均达到显著差异,但是两地适合度差异不显著,显示出很强的可塑性;2)阴阳两地小拟南芥在叶重与茎生叶数、花序重与花序长、茎重与株高、地下重与主根长、角果重与角果数均表现为极显著相关,表现出很强的特征整合能力。根据现代植物可塑性研究成果,对新疆境内小拟南芥光适应性特点及进化趋势进行了分析。
